Be; rt. known that I,'""GU1sEPrE JOSEPH BAUMSTA'RK, a citizen (if-France, and a residente-f,l Bradley Beach, Ain the cofunty of Monmouth' and Stateof New Jersey, have and useful Improvements in Internal-Combustion Engines, of Awhich the following is av sp'ecication.

My invention has for its object an engine nal vcombustion engines in which a plurality l:of cylinders lrevolvev around a common or shaft.' A l My invention relates to that class of inter- ,of the class `described in which the power of the engine Jmaybe'..-varied by increasing or decreasing the number of explosions foreach revolution of the engine, that is, thel power may be varied without varying the speed of lthe enginel or t'ielnuniber of revolutions of 'of power being possible whilethe Aengine, is

My inventionhas for its l.further `object an engine of the 'class described freeii 'from 'v crank shafts, wrist-pins, or gearing,` thus .overcoming the friction, wear-and practical difficulties and troubles incident to'their use. The engine of mv invention is therefore much more easily and cheaply kept in proper working condition, and a.g considerable saving. made inthe cost ofi-'gas consumption. Al further obgect of my inventionls an en- Vgine of the class'deseribed lin which the danger ofI centrifugal force is 'almost entirely overcome, thus making it much safer to operate. f e L lA further object of. my ina ention is an e11- gine of -the class described which is capable of both a` forward and reverse movement.

A further object of my invention 'is an engine of the class'described in which all of thevalves, wit h the exception'of the exhaust valve, work automaticailyfby the gas pres- :sure of the piston movement' and in which.

the exhaust valve worksfrne'chanically and in unison with the spark timing device.

A further object of my invention is an en gine of the class described, in which all 'die 0 moving parts are readily and cheaply re-` placed and easy of access.

My inventinfl-i-as for its further object an engine ofthe classidescribed in which the varying of power may beeasily and noiseles'sly accomplished when the engine is run- ,th'pistons and the shaft,

These cani 'of' stopping ning or at rest, and in which self-starting maybe easily and readily obtained'.

The engine of my invention comprises a plurality of piston cylinders rotatable around a common axis and carryin therewith a shaft for power purposes. he explosion or combustion chambers are between the free ends of the 'pistons with their piston rods being extendedL away from vthe shaft. Completely surrounding the piston cylinders'isl a' series of cam run-ways connected together by Steps. run-ways are ,non-rotatable but capable ,of aperpendicular movement across the axis ofthe piston cylinders. The ends of the piston rods,l fitted withsuitabie rolling means, run around one of these cam'.

run-ways when the-engine is in action, the

plston rods being pressed against the runway by suitable means. The .pistons will thus take a reciprocating movement dependentiupon the particular-shape of the cam run-way in which they shifting the plurality of run-ways, the cylnderi'Ods will ride acrossthe step and then run in the new cam run-way thus brought to atenten Aug. 31, reis.

are running. By

bear upon them. If this second run-way be a camof different shape from the former it is evident that the pistons will assume a different speed.. of action. 'if for instance the engine is a four-cycle, and the rst cani runway requires two revolutions of a piston cylinder, in order to exhaust, charge, compress and explode, and the second cani run-way is of such a forni as to allow of all four of these operations during one revolution of a cylinder;V it is evident that the power of vthe 'engine has been doubled without increasing its e speed or the number 'of-revolutions' of the cylinders, and Ithat this` has been accom-' plished without stopping or siowing the e'nglne. A.

in 'the known engines ofthis class, great danger from centrifugal force is experienced on account of the rapid revolution of the cylinders, which: are free and unprotected at their ends farthest from the center. In my device this danger is entirely overcome, as the cam run-ways with-their steps act ,asia bracing means, cviinders run between the shaft andtherun ways. f *fj- By ixedly attaching the piston cylinders to the power shaft bustion or explosion chamber at the linner and the rapidly? revolving i and positioning the eoniliw 'suction cause end of the' piston cylinders, I obtain the rotation of the shaft'without the use ofany shaft-calms, crank-shafts, wrist-pins or gearing," all of which are subject to mucha means whereby all of the valves in my engine, with the exception of the exhaust l valve, are moved automatically by the gas pressurecaused by the movement of the piston. To accomplish this I make use of an intake cylinder and an auxiliary gas cylinder, both of which are connected to the piston lcylinder by spring valves capable of being opened and closed by the pressure or suction caused by the movement of the piston. The intake cylinder is directly connected with the source of explosive ases and separated from the cylinder behin the iston by a valve capable of being opened hy the suction,V caused b y,thewdownward movement of they iston.

The upper )art o the auxiliary gas cylinder is separate from the cylinder behind' the iilston by a valve ca able of being opened by t e pressure cause b` the upward movement of the piston, an the lower end of the auxiliary gas cylinder is separated from the cylinder in front of the iston, that is the combustion or ex' losionc iamber, b means of a valve ca )ab e of being openedy by the by the upper movement of the piston, Therefore, when the piston descends, the auxiliary gas. cylindei' is closed and fresh gas isdrawn in behind the piston, andl when the piston asceiids the y intake cylinder is closed and the gas behind the piston is forced into the explosion chamber, except when the lower valve of the auxiliary gas cylinder is kept closed lby Vthe force 'of the exploded gases when the gas from behind the piston is forced through the auxiliary gas cylinder into the auxiliary gas chamber. I v

' It is evident that a shifting of the piston rods from one cam run-way to another, will cause a change in the number of explosions to each revolution of a cylinder and hence it is necessary that the timing of the spark and the operation of the exhaust valve be changed to agree with the new'nuinber of explosions. This I accomplish by means of a commutator and exhaust valve mechanism operated l) a, plurality of cams similar to `those of t e lcam run-ways, a shifting of the cam run-ways being automatically ac-.

a companied by .a'corresponding shiftinur of thecams operating the spark timer un exhaiist valve, hence the spark and the ex haust will always be properly timed for lthe he auxiliary gas. cylinder is direct y connected with a cham-l ber for the store" of thel explosive gases.l

l1. Fig. 7 is a vertical section, throughithe way 76 of Fig. 3. Fig. 14 is a diagrammatic *fester-mvg! gas explosions, no matter how the latter be increased or decreased.

The starting of an engine of my device is much more easily accomplished than that of the ordinary engine of this class, becau 7g in some of the cam run-ways, two, three or four cylinders are in compression at this same time, one at least of which will be practically at the sparking point, and n supply of compressed gas is a ways readyto be ed to the cylinders from. the auxiliary gli chamber, and hence but slight movement -is necessary to explode the ghlin one 0f the cylinders and start the engine. M

It will be seen that an engine of my in- .o vention of low power can be readily and, easily converted into an engine of power, while running, at the lower 'expense of construction of a low power enf gine, with all its advantages o reduced i weight, cheapness of operation, ease of mxi iiipiilation, and certainty'of actioncoupled u with the advantages of its conversion into v an engine of ments. m rlhe accompanying drawings, illustrate by way of example, one form of an engine con structed according to Lmy invention.

chamber 32, this exhaust chamber 32 extending completely 4around Y. the kshaft and sleeve and being connected with'each of the 1 exhaust cylinders. f 95- Surrounding the plurality of piston chambers is a plurality tif-varying can-1 runways 76, 7", 78, Figs. 3 anda, connected by the steps 79, '79, so arranged that the Wheel 38 -of each piston rod 35 Will run therein and 10Q abut thereon, the' abutment being main. tamed 'by the'sprmg 42, the gas pressure behind the' piston 33 and the' centrifugal 4 force incident to the rotation of' the ,cylinf dersl during the running of the' engine. The 105 Cam run-ways--are nonrevoluble butc'apable of a transverse movement in order :to change the wheel 38 from one run-Way to another'. The g mechanism producing fthls transverse movement of the Cam run-waysis show'n in 11o Vment AWith the shaft 15 andsleeve 16 by thecr'oss pieces 86, 86, 87, 87, carrying the shaft 120' bearings 88, 89. F ixedly attached to each of the other -ends of the side bars 85, oi`

the frame is a supporting-upright 91, 91, byx means of the bolts 92, 92.v At a fixed dis#` tance from the side bars 85, 85, a bar 93 is 125 revolubly attached to the uprights 91, 91, by means (if the sleeves 94,- 9J:A and a lever 95` Ais xedly attached tothe bar 98. A link system 96, 97, 98, 99 is iixedly attached to the bar 93 by the link member 96. Thelink -i3()l 99 is fixedly attached to the plate 80' and theA sleeve 81 by means of the thumb-screws 490, 90, the link system bein `so arranged that a partial revolution of t e bar 93 will slide the run-ways '76, 77, 78 and steps 79,

79, along the bar 83. vUpon the cross bar 87, a spring tongue 100 isattached to spring into-the indents 101, 102, 103 upon one of the linksv 98 and lholdthe link from accident-al.. movement. A. second link system '104, 105, 106 is attached to the bar' 93 by the link 104. Upon the bar 87, a spring-tongue 108 is attached to spring into the indents 109, 110, 111, in the link 106 and hold the link from accidental movement. The brace plate 112 holds the link 98 from lateral displacement, and the brace plate 113performs /the same function -for the link 106. The

"lengths and arrangementsof the two link l systems are such that a partial revolution of the bar 93, will cause .th'e first link system to move from one indent to another of the link 98, relative to the tonguerlOO, as the second link -system moves from one indent to another of the link 106 relative to the tongue108. 4

The shaft 15 loosely carries the cams 114, 115, 116, connected by the steps 117, 117.

This plurality of cams and steps does not revolve with the engine but remains stationary. A spiral spring 118 has a tendency to spread them away from the,abutment 119, and they are moved along the shaft 1 6 and retained in a fixed position by means of the 'cordance with the position of the pistons due to the particular cam run-way operating upon the piston-rod. IrpFig. 1, the commutator comprises a member 73, a ratchet wheel 122 and a. member 123, integral to each other, revoluble upon tbl shaft 124, which is held by the supporting vmembers 125, and which is capable of perpendicular movement. The pawl 126 pivotallyat# tached to the support 127 hy the pivot 128,l

allows of the revolution of the'commu'tator land its retention, a second-pawl not shown` in the drawing being Auponthe reverse side of the ratchetwvheel 122. The wheel 129 attached. to the member 123 b v meansfof the' arm 130, allows the commutator to follow lthe eam,-116, as theJ- commutator revolves with theengine, thus raising and lowering fthe commutator members .to agree with the shape of the c'am 116. Upon the member i 123 is a seriesof electrical connection points 131 Ito connect with the point 132, which is in turn connected -with the source of electrical power. The oints upon'the member 123 are so ariangerthat'they will connect with the point 132 at certain positions of the roller 129 upon the cam 116. The shapeof the member 73 is such that the raising of the whole commutator member will openl the exhaust valve 57 by raisi the rod 72, operating the-pivotal member .0 and press ing down the valve rod 69 at the proper time for the exhaust gases as overnedby the cam movement. It will- 11S -be se'en that the revolution of the wheel 129'around the cam 116, will fire the explosive gases and operate the exhaust valve at certain predean examination of Figs. 3 and 4, that whe'n the bar 93 is partially revolved by means of the lever 95, the cam` run-wa s 76, 77, 78

The effect of the vcam run-ways and the shifting devices while the engine isvrunnin may be seen from Figs. 3 and 4. In Fi the wheel 38 at the top of the piston ro in the piston chamber 19 is running around a slightly depressed groove in the run-way 78,

By moving the lever 95, the cam run-ways and the commutator device are shifted into the posi- .tions shown in Fig. l, the wheel 38 passing from the cam run-way 78 to the cam rum way 77 across the intervening step 79. piston is .now being controlled by the runway 7 7, va diagrammatic cross-section of .which is shown in'lfig. 12, and the commu- Thee tator device and exhaust control 123 islrun ning uponthe cam 115, to properly time the spark and exhaust. During the passage of the piston .rod wheel across the s`tep'79, the commutator prevents theformation of an electric current. The dotted line of Fig/1 showsthc position .of the camrun-way 76 in ,Fim 3,v a diagralmn-.itic cross Section of theV caihrulrivay 76 is shown in Fig. 13. A 'Asall of the valves,with the exception of 'the exhaust valve, which is mechanical, are automatic and operated' by the pressure of the gases and the suctionaoffthe piston,lit .is evident that any form of a cam run-way may be employed in the 'operation of the piston if the proper comlnutator and ex- /haust valve mechanism vare usted, but in the drawings the three forms of run-ways illustrated in Figs. 12, 13 and'lfi are emplyed. The cam of Fig. 13 is circular but eccentric, that of FigflZ is elliptical and that two revolutions for each explosion, or three.

v and a half explosions for each revolution of a seven vcylinder engine. 11n the form of. Fig. 12,'Jeach cylinder Awill have oneexplofy sion .for each revolution, or seven explosions for each Arevolution ofufa vseven ycylinder engine, whiletlieform shown in Fig. 14, will give ten .and a half i' explosions for. each `revolution ci the engine. y

A clear description of the operation of the piston, and thevarlous valves, of the intake and exhaustion of the gases and of vthe ac-` tion of the cam run-.way while the engine is running inay be obtained vfrom Fig. 2, which diagrammatically illustrates l the course of one cylinder during one revolution aroundv the eccentric cam run-way 77 shown in Fig.

12. it the point 133, the piston has reached its highest positionv and on its downward movement exhausts the spent gases through the exhaust valve 57 into the exhaust cylinder .G and through 75 into the exhaust chamber As the piston descends it opens the valve G12- of the intake cylinderl 60 and draws in fresh ,gas throughthe pipe-61y from the intake chamber 27.. This downward movement of' the piston also retains the valves i5 a nd 50 otheauxiliary cylinder 43 in aclosed condition'.4 The piston is thus discharging the spent gases and drawing infresh gas behind itself. At the 'point 134 Ithesaine ,conditions continue. i After passing the point 135, the piston begins to ascend and as at the point 136, the piston in its up-fv ward movement, closes-the Valve 62 ofl the v intake cylinder 60 and the exhaust valve 57 ci the exhaust cylinder 65, and 4opens the valves and 50 ofthe auxiliary cylinder" 4B, forcing the gases behind it through the auxiliary kcylinder 43 and drawing them. into the combustion.chainberj j if this amount oi gas is insuihcient, additional gas is drawn frein ythe auxiliary chamber 3l through the: pipegfi. It the amount ci, gas is greater than required it would be forced back into the auxiliary chamber This operation continuesas the piston passes from the point 1% to the point 138. As the piston passes from the point to the point 14.1 it descends and compresses' the gas in the con1- bastion chamber by keeping the valve 57 of the exhaust cylinder' 65 closed, and closing the valves 453 and of the auxiliary'cylinme time opening the; valve 62 oi.- Lii; :nt: ylinder'lGO anddrawing in a new charge behind it. vThe explosion-taires place at the point 141.', and the upward movement oithe piston fromy the point 141 to theipcint 133,' closes the valve 62'offthe' that the, intake chamber is 'capable of sup- Y plying all ofthe piston cylinders with fresh gas as theyneed it, and the Aauxiliary chamj boris always capable. of iving or receiving the gas to all of the cy lnders "asrthey require. y Y' .It is evident that an enginecan be made according to my invention with only one cam run-way havingV all p of the advantages of the engine illustrated with the exception of the changing of power. `I do not limit myself number, shapesizcr arrangement of parts `to the particular illustrated as it is evidentthat they may be' greatly variedl without' going .beyond the scope of my .inveuliiofi4 asY dsribed and' f claimed o v i I What is claimed, is: y
